This invention relates to door closers of the type intended primarily for use in connection with screen doors to the end that such door will be returned to its closed position following the 5 opening thereof.

An object of the invention is to improve generally upon such types of door closers as are now known and used; and the invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view illustrating the application of the invention.

Fig. 2 is a top plan View illustrating the application. of the invention.

Fig. 3 is a perspective View of one of the frame members forming part of the closer.

Fig. 4 is a perspective view of a comlemental frame member forming part of the door closer.

Fig. 5 is a sectional view illustrating certain details of construction hereinafter more fully referred to, and taken substantially on line 5-5 of Fig. 1.

Fig. 6 is a perspective view of a link member forming part of the invention.

Referring more in detail to the drawings it will be seen that in the preferred embodiment thereof the door closer comprises a pair of complemental frame members 5 and 6.

Each of the frame members 5, 6 is formed from a single length of wire bent into a substantial U to provide a pair of elongated legs 'I'Z which at the closed end of the U are connected by a bight 8 that has its intermediate portion bent inwardly to extend between the legs I in a plane normal to the legs and provide a loop 9.

At the free extremity thereof each leg lis bent laterally relative to the leg and then reversely bent about itself to provide a laterally extending eye H).

The members 5 and E are arranged in assembled relation for relative sliding movement with the legs I of one member working through the eyes I [l of the complemental member as shown.

The members 5 and 6 are normally urged to slide in reverse directions to what may be considered a retracted position of the door closer through the medium of a coil spring H.

Coil spring I I has the respective opposite ends thereof hooked or otherwise engaged with the loops 9 of the respective members 5 and 6 as shown.

Also each of the members 5 and 6 at the bight end 8 thereof has pivotally connected therewith a substantially U-shaped link l2.

Each link i2 is formed from a single length of wire bent into a substantial U and at the open end of the U the legs of the link are bent back upon themselves to provide eyes i3 that engage the bight 8 at opposite sides of the elongated loop 9.

For properly engaging the closer with the screen door or other closure Hi there is suitably mounted on the frame of the door at the inner side thereof a hook it of any suitable construction.

The link I2 associated with one of the frame members, for example, the frame member 6 is engaged with the hook it in a manner clearly shown in Figs. 1 and 2.

For completing the mounting of the closer there is provided an attaching bracket it in the form of a metal strap that is bent upon itself and fastened to the door frame it through the medium of screws or other fastening elements l8, The attaching bracket it prior to being so secured to the door frame if is trained or passed through the link l2 associated, in the present instance, with the sliding frame member 5 as also clearly shown in Figs. 1 and 2.

Thus in actual practice the door closer is mounted on the door i l and door frame ll as shown in the drawings.

Now it will be seen that when the door M is swung outwardly to open position the frame member 6 will slide relative to the frame member 5 against the action of the coil spring H, and after one has passed through the door, the spring. II will then act on the frame members '5 and E to cause the same to move to the normal position shown in Figs. 1 and 2 resulting in the door M being caused to swing on its hinges to a closed position.

Thus it will be seen that I have provided a simple and inexpensive construction of door closer or spring which can be readily and easily mounted for use, and when in use will admirably serve for the purpose intended.

Having thus described the invention, what is claimed as new is:

A door closer comprising a pair of elongated substantially U-shaped members each having the ends of its limbs bent to form a closed loop with the loop extending at right angles from each limb, the bight of each U-shaped member being bent to form a U-shaped loop which extends inwardly between the limbs and parallel to the limbs, the limbs of one U-shaped member passing through the right angular arranged loops of the other member to slidingly connect the two members together, a coil spring having hooks at its ends engaging the U-shaped loops of the bight portions of the U-shaped members and tending to move the two U-shaped members together, a pair of small U-shaped members having eyes at the ends of the limbs, the eyes of each small U-shaped member having passed there through those parts of a large U-shaped member which connect the U-shaped loop with the limbs thereof and a pair of brackets one receiving the bight of a small U-shaped member and the other the bight of the other small U-shaped member.
